Cal Mod Ionrock Language

[Seppe]

Hello,
i changed the calender to v2.1 because i need german as language.
Well, i have the module in the backend but when i "klick" on main calender i get the error message
"Error: 1146: Table ´db118317776._phpwcms_cm_events´doesen´t exists,
also if i try to open the calender in the frontend.
When i "klick" on Language Packs in the backend -> There are no language packs currently installed.
I thougt english is default.

What´s wrong ?

Thanks for your Help !

Sepp
